Patented Mar. 31, 1931 UNITED TES ROBERT L. ANTHONY, OF S'WANSEA, MASSACHUSETTS, ASSIGNOR TO B. B. & R. KNIGHT CORPORATION, GE PROVIDENCE, .R-I-IODE ISLAND, A CORPORATION OF RHODE ISLAND EDUCATIONAL DEVICE Application filed January 13, 1930. Serial No. 420,461.

My present invention relates to educational devices, and has particular reference to devices for disclosing processes of manufacture and the like, particularly of well known articles.

One object of the invention is to provide a convenient educational article which groups together pictures of different operations or steps, descriptions of the operations, and a sample of the effect of the operation.

Another object of the inventionis to provide a designating index which indicates the relative sequence of the particular operation in the total manufacturing procedure.

A further object is to provide a series of consecutive educational articles which together disclose the complete manufacturing procedure.

With these and other objects and advantageous features in view, the invention consists of novel arrangements of parts more fully disclosed in the detailed description following, in conjunction with the accompany ing drawings, and more particularly set forth in the appended claims.

In the drawings:

Fig. 1 is a plan view of an educational article disclosing one step in the process;

Fig. 2 is a central vertical section thereof; and

Fig. 3 shows a series of consecutive articles disclosing a complete manufacturing procedure.

In disclosing the steps entailed in forming a completed article, it has been found desirable to group a description of a single step in the formation with a graphical characterization of the step, and an example of the effect produced by the step. I have therefore devised a series of educational articles, each disclosing a single step and the series disclosing the consecutive steps, each showing the step by description, by illustration, and by a sample of the resulting effect; and the folthecomplete manufacturing or completing process, and a representation or' mark 17 which designates the sponsor of the educational articles. 1

The complete series indicated in Figure 3, thus fully'explains how the finished, completed product is obtained, by description, by visual description, and by actual illustration of the effect of each operation or step on the material.

To group the desired eifects-of each step, preserve them in a uniform relation and to guard against'wear and tear during use, a

base sheet 10, shown in Figure 2, is printed or otherwise marked, as shown in' Figure 1, and a sample or specimen of the materlal 1s positioned thereon, the material illustratedin Figure 4: being wound on a cardboard 19 for convenience in securing it to the base sheet, and a transparent protecting cover 20, preferably of celluloid or the like, is positioned over the base sheet, and the base sheet and cover are secured together by edge taping 21 or the like.

A specific embodiment of this invention is illustrated in this application which is the steps in the manufacture and finishing of cotton fabrics.

Each of the steps is depicted on an article designated in the drawing by Roman numerals I to inclusive, and each step is arranged as heretofore described.

, The'name of the step in the process of finishing cotton fabric with the descriptive phrase appears on each article as follows:

I Cotton Field Over eight million of 500 lb. bales of cotton are used in the United States each year Lapping Cotton opened, cleaned and put into lap form carding The important processes of cleaning and making fibres parallel Roving The ends are drawn down finer and finer and twist- III , ing begins V Spinning The last drawing and twisting process, the production being warp or filling yarn Warping The warp yarn wound parallel on beams in preparation for weaving slashing The warp yarn is passed through a boiling size and is then ready for the loom beam Weaving V Combining the warp and filling to produce cloth Inspecting An extra insurance in the production of satisfactory clot X Bleached Cloth Thousands of yarns are temporarily piled in bins after being fully bleached Mercerizing IS)tre r i.g, 'thens fibres and adds sheen to the fabric ,veing The cloth is passed and repassed through jiggs Printing Patterns having from one to seven colors are printed in one operation I Tentering The cloth which has contracted in width in bleaching is again brought out to correct Width VII VIII

XV Calendering This is the final finishing process; ironing is done under heavy pressure by heated rolls XVI Packing Goo%s1are doubled and rolled and identified with la e s.

Each of these articles has a numeral designating its place in the sequence of steps and a picture is also present showing the room or place andthe means or machinery for accomplishing each step in the process. For

example, I shows a cotton field with the cotbefore an inspector; X, A view of the bleach- 7 ing room with means for delivering the cloth into bins; XI, Mercerizing machinery; XII, Dyeing vats and machinery for passing the cloth into and out of the same; XIII, Printing machines, XIV, Tentering machines;

XV, Calendering machines; XVI, Machines.

for delivering the cloth and tables where 01)- eratives are rolling the cloth into bolts and the like.

Also a sample of the goods appear on each article after the operation or step depicted thereon is performed and by comparing one sample with the next an excellent visual realization of just what takes place on the cotton itself is obtained.

W Each one" of these cards ora'rticles is here illustrated as separate, but a box or suitable container (not shown) is provided in which all may be placed to provide a unit assembly, or any suitable means may be provided for holding the cards together, such as tape to form a folder arrangement or the like to preserve the unity of assembly of the diflerent cards which form the steps in the operation of the finished product desired.

My improved educational device is simple in construction and is very eflective in explaining how completed products are obtained. While I have described one specific construction illustrating the principles of my invention, it is obvious that desired changes in construction and in arrangement may be made, within the spirit and the scope of the invention as defined in the appended claim.

I claim:

An educational series for visually and descriptively describing steps in the completion of a product, consisting of a series of separate cards adapted to be juxtaposed for direct comparison, each card having a pictorial representation thereon of one manufacturing step, the title of said step, a written description, a physical example of the efiect produced by the step, and an index mark showing the relative position of the step in the series, whereby the successive steps and their effects may be directly compared.

In testimony whereof, I aflix my signature.

ROBERT L. ANTHONY.
